Answer:
All of them.
Explanation:
For considering the annuity formula we can determinate all the proposed factor:

C represent II the amount of each cash flow
r = represent the discopunt rate
while time or "n" represent the numebr of cashflow we have to calcualte the present value.
The timing refer wether the payment are made at the beginning or end of the period.
When made at the beginning it is an annuity-due
and the (1+r) factor multiplies the previous formula to represent the addtional period of capitalization each cashflow has or the one period less to discount for each cashflwo in cases of prresent value.
Answer:
All of the above are true.
Explanation:
The law of diminishing returns was first formulated by the classic economist David Ricardo. It presupposes a technical relationship between input and output, which is not scientifically demonstrable but only empirically. In practice, in a generic production system, at any contribution of any factor, that is, land, labor, capital, machines, etc. there is no proportionally increasing production increase.
Normally it is assumed that the law does not always come into operation but only when the variable input exceeds a certain threshold. For example, the increase of workers on an assembly line certainly allows a proportional increase in production, but only until the entire system begins to suffer from malfunctions due to logistics or work organization, precisely because of the its getting bigger. Large industrial plants have shown that they must be divided into sections, however coordinated, precisely because of the decreasing returns. This is because the increase in the number of workers and the mass of the plants does not correspond to a consequent increase in production.
i not sure but cyclical makes more sense.
That opportunity was created by political actions and regulatory changes, government subsidiaries. An opportunity is a favorable set of circumstances that creates need for a new product service or idea. An opportunity should have essential qualities such as attractive, timely durable and anchored in a product, service or business that adds value for its buyer or end user.
